How does bacterial transfomation using a restriction endonnuclease occur? What is the size of the fragment formed by a specific endonuclease?

Summary: Deoxyribonucleic Acid (DNA) is the molecule of life. It is composed of a nucleotide, made up of a sugar (deoxyribose), a phosphate group, and a nitrogen base. Their can be 4 nitrogen bases: Adenine, Guanine, Cytosine and Thymine. Adenine will always pair with Thymine and Guanine always pairs with Cytosine. Thus %A=%T and %G=%C. It is the order of the nitrogen bases that give each individual their own unique look, since DNA is transcribed and translated into proteins which eventually give an organism its look or phenotype.
